Description

Adjusting mechanism of drop roller

Technical Field

The utility model relates to the technical field of printing equipment, in particular to an adjusting mechanism of a drop roller.

Background

Some printing presses require the drop roller to contact the plate roller for ink delivery during printing operations and to be out of contact with the plate roller during non-printing operations, which requires easy adjustment of the drop roller for movement. In addition, to better meet the job requirements and print quality, to ensure proper contact pressure of the drop roller, fine adjustment of the drop roller is required.

CN207128400U discloses a drop roller adjusting device of a printing press, which comprises a frame, a cylinder seat, a connecting fork, a rotating arm, an adjusting arm, a rotating shaft, an adjusting bearing and a bearing seat; the adjustable lead screw adjusting device is characterized by further comprising an adjusting lead screw, a lead screw adjusting seat, fixing blocks and an adjusting rotary table, wherein the adjusting lead screw is arranged on the rack above the air cylinder through the lead screw adjusting seat, the fixing block is arranged on the rack on the front side of the adjusting seat, the front end of the adjusting lead screw penetrates through the corresponding fixing block and is connected with the adjusting rotary table, and the rear end of the adjusting lead screw is correspondingly positioned above the connecting end of the adjusting arm and the connecting fork. However, the above described drop roller adjustment device is complicated in structure and inconvenient to adjust.

In the figure: 1. mounting a plate; 11. a strip-shaped hole; 12. a guide rail; 2. a movable bearing seat; 3. a movable drop roller; 4. fixing a bearing seat; 5. a fixed drop roller; 6. a first cylinder; 7. a fixing plate; 71. a second cylinder; 72. a guide post; 8. a support plate; 9. a first gear; 10. a second gear.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-3, an adjusting mechanism of a drop roller comprises a liftable mounting plate 1, a movable drop roller 3 mounted on the mounting plate 1 through a movable bearing seat 2, and a fixed drop roller 5 mounted on the mounting plate 1 through a fixed bearing seat 4, wherein a strip-shaped hole 11 is formed in the mounting plate 1 at a position corresponding to the movable bearing seat 2, guide rails 12 in sliding fit with the movable bearing seat 2 are arranged at two sides of the strip-shaped hole 11 on the mounting plate 1, and a first air cylinder 6 connected with the movable bearing seat 2 is arranged on the mounting plate 1; a fixed plate 7 is arranged above the mounting plate 1, and a second air cylinder 71 connected with the mounting plate 1 is arranged on the fixed plate 7; a support plate 8 is arranged below the mounting plate 1, and a guide post 72 arranged by penetrating through the mounting plate 1 and the support plate 8 is arranged on the fixing plate 7; a first gear 9 is connected to the end of the movable transfer roller 3 and a second gear 10 is connected to the end of the fixed transfer roller 5.

By adopting the technical scheme, when the printing roller is used specifically, the movable ink transfer roller 3 can be contacted with an ink tank (not shown in the figure) which is arranged below the movable ink transfer roller 3 and stores ink, the movable ink transfer roller 3 is transferred to the fixed ink transfer roller 5 after the ink is adhered to the movable ink transfer roller 3, the fixed ink transfer roller 5 transfers the ink to the printing roller (not shown in the figure), and the printing roller prints paper, films and the like to be printed.
